which turbo for around 400bhp semi-forged 2.5
so im looking for around 400bhp give or take 10bhp from my hawk sti
it has....
2.5 built by scoobyclinic with closed deck inserts
mahle 2618 pistons
std rods with arp rod bolts
new crank
new acl race series bearings throughout
cosworth headgaskets
assumed 11mm arp head studs
rebuilt heads with upgraded valves/springs and retainers
engine has covered 8k @ 351
ran on royal purple oil since build with 2 x oil changes so far
other modifications are....
hybrid vf43 from cr turbos
japspeed fmic
scoobyclinic induction kit
full decat with 2.5 inch exhaust and vortex backbox
std headers and up-pipe
denso 750cc injectors
walbro fuel pump
extreme lightweight flywheel and ap racing clutch
looking for a suitable turbo to reach around 400bhp, though about the sc42 but quite expensive @ nearly £1800
any other suggestions?
cant run massive amounts of boost due to rods being std, also car is a fast road car only-no track work

Already discussed rods on another thread buddy, won't be changing them unless engine decides to **** itself.
Mdx also a expensive turbo though, I'm sure there are blowers out there for around 1k that will do the job. Will speak with Owen developments and also engine tuner about their t36 unit

Gotta work out if the sc42 would be 600 quid better than the t36 from engine tuner as they come in at around 1100 smackers and offer between 380-450 bhp.
Also forgot to mention that I will be changing the headers for either ported as performance sti ones or a set of rcm ones if I see a set at a decent price.
Thanks guys

How about td05 18g?
I picked up my Andy Forrest version for £500,its making 380/380 at just under 1.5 bar on a 2.1,with slightly better fueling it could have squeezed a little more out.
So could get you just under the 400 mark on your set up.
I don't think you can beat it for bang for buck.

And you can't beat the sc42 as the drivability is awesome, and I think I was at around 440hp on my last map.
This video was when I first fitted it and without avcs working and at just over 400hp at the time, few Tweeks needed to finalise it after some issues but just look at how quick it flys round the rpm gauge.

The drivability is awesome, makes a excellent point to point car or rapid daily (if I didn't want that so much I'd of chosen a bigger turbo like I was going to do, but it just wouldn't be as Rapid as that, so lower hp is sometimes faster on the right roads).
On your 2.5 is will spool way faster. May spin all 4s in 4th lol, mine span in 3rd on damp roads lol.

now then forgive me if im wrong but that seems a lot of boost to be running on the standard ecu and my std rods. i was always told to buy the smallest turbo to reach my goal so maybe an sc38 would be a better choice over an sc42 as i wouldnt be running as much boost then and still make around 380+bhp.
